I have a seller around me that wants me to pay 285 for a 5 bin rack, it comes with the heat cables installed. I think it would be a lottt cheaper for me to just build one by myself. the only thing is i really do not like working with electricity, and the videos i've watched on installing the flexwatt kind of scares me (with the risk of shock and possibly fire?) would it be worth it for me to just buy them already made?

i live in ontario by the way. also where would i get flexwatt?
